Hspring --supporting bar and to means vfor #mounting-and adjusting said bar.

.The -main Yobjects of `said inventlonygenlorally stated, vare yto provide simple and efcient means of the characterspecified which may :be manufactured at small cost n and-enable the parts to be readily assembled .and disassembled when desired.

'l`o the above vand other ends which will hereinafter appear, .my invention consists ofthe features of construction, arrange-` ments of fparts and combinations of `devices set forth in the following -.desoription :and

particularly-.pointed :out :in the appended 'cl-aims.

In the drawings wherein :like reference characters indicate corresponding vparts in the;different views,

Figure'l vis a fragmentary vertical fore and aft sectional vview showing yonly so ymuch of Va ,typewriting machine asis .necessary to `illustrato my invention. Fig. 2 is a transverse sectional view yof the same taken on the line -m of Fig. 1 and looking in the direction :of the arrow at said flin'e.

In the present embodiment lof ymy invenftion a system of key -levers for kthe type-actions, etc., constitute the .actuating members to which .the actin-ning springs are applied. It will be understood, however, that fthe Vini vention may be'employed wherever found available 4and that Athe character of the actuating members to which :the Yreturning springs are attachedis immaterial.

`The frame of the machine comprises a base l which .is lsuitably supported, Yinv a manner not shown, a Afulcrum bar vor rod 2 tor :the actuating members, which .in the present instance v.comprises a series of key `by :the reference lnumeral 5.

into :the springs.

'turned Jdownwardly `the bar is'fc'ausedrto folllow Vby the action of ithergang xof springs-and le-vers f3. These flevers, kas shown, extend' f Y :fore and aft of fthemachinexin parallel .arlrangement, each liey fleve-rxbeing connected V`.to 'a contractile returning spring :4. vThe -upperiends of :these springs-.are connected :to/a:hollowsupporting-bar which is ourved :incross sectionI and .is designated; asza whole l l This bar 1s preferably made of sheet metal and isistruok up into tubular yor :substantially -oval or f.Csshaped formation in '-.cross section. |-Thev lbar extendstransversely facrossthe machine and is perforated near fthe endsfand .at ithe under side thereof to receive 4'the lcylindrical `reducedends '1G of fthe vset screws 7. These :screws work in tapped Yop'eni'no's in fthe `base of 'the'mach'ine forl vertical'. adjustment. EBy

reducing the ends 6 `of these :screwssthouflders 8 are fproviided :thereon for cooperation `with the body portion o'f'thexsupporting bar '5 at fthe underside thereof.' 1t willbe iun-v` 'derstood, therefore, 4,that :the :bar is `supported only attheen'ds thereof-and that lan adjustment of [the :screws 7 isdeectifve 15o-'give a ybodily adjustment of I'the :supporting 1b ar V5,

:raising or lowering the la'tter `to effect A a simultaneous ,adj ustment fofsthe force 'of all of` the-contractile=springs connected to said bar. When thescrewsfar'e forced :upwardly 'the' kbar -5 1s :raised and more tension :put

When the screws lare" 4at `the fsame time "the :tension `of the springs is lessened.

--One edge-of the sheet metal Aplate "from which the supporting bar lis formed is p=rojections,-=hooks or ftines '10. v/Vhen the bar formed as shown Ythese tinespartake slotted .transversely at 59 Vto `form 'a series of 'Y wof `the `curvature of the bar andare fcon- 'ta-ined within the outline fthereof :and Yconstitute' hookslike :members vover Keach of :lilte projection ywandthe V"apposite edge 13 Y of the `:supportiqng bar :to facilitateengagethe bottom wall of the slots 15. The bar is .prevented from moving fore and aft of the machine and from turning by the forks or ways in which it is seated and the reducedv ends v6 of the screws taking into the apertures in the bar prevent an axial or endwise movement of the bar. rl`he springs also assist in keeping the bar in proper working` position. j

In assembling the parts it is merely necessary to introduce the supporting bar in place by dropping or moving it transversely of itself through the open ends of the slots 15 into its bearings or ways and seating it on the reduced ends of the adjusting screws. Previous to this, if desired, the upper ends of the springs 4 may all be connected to the hooks 10. Thereafter the lower ends of the springs may be hooked into the holes 16 in thekey levers. Of course, though, if desired, the springs may first be attached to the key levers and subsequently attached to the hooks on' the bar.Y When the returning springs are detached the supporting bar may be readily removed by merely lifting it from its position in the open-mouthed ways or f slots in the base of the machine.

Various changes may be made in the con-V the ends of the bar are slidably mounted,

means for effecting a bodily adjustment of the bar in said ways, and springs each connected at one end to one of said tongues.

2. In a typewriting machine, the combination of ahollow supporting bar which is substantially C-shaped in cross-section and is provided with a series of engaging tines along one edge and within the outline of said bar, key actuated members, and con- -metal supporting bar provided with engaging tines and mounted at its ends for bodily adjustment in said ways, the end portions of the bar having each a greater dimension longitudinallyof its slotted bearing than transversely thereof, whereby a turning movement of the bar in its bearings is prevented without interfering with said bodily adjustments, and springs connected to said' tines.

4. In a typewriting machine, the combination of a machine frame having open ended slots formed therein, a supporting bar received and guided in said slots and adapted to be inserted in or removed therefrom through the open ends of the slots, set

screws which extend through tapped openings in the bottom walls of the slots and bear at their end portions against the supporting bar to effect an adjustment thereof in the slots, and returning springs connected to said bar.

5. In a typewriting machine, the combination of a machine frame having an upwardly extending lug on each side of thebase thereof, said lugs being slotted to form ways; a supporting bar received and guided in said slots; means for effecting a bodily adjustment of the bar in said slots; and returning springs connected to said bar.

6. In a typewriting machine, the combination of a machine frame having an upwardly extending lug on each side of the base thereof, said lugs being slotted to form ways; a supporting bar received and guided in said slots; set screws which extend through tapped openings in the bottom walls of the slots and bear against the supporting bar to effect an adjustment thereof in the slots; and returning `springs connected to said bar. Y

7.' In a typewriting machine, thev combination of a machine frame which has an upwardly extending lug on each side of the base thereof, said lugs being slotted to form ways; a tubular sheet metal supporting bar received and guided in said slots and having Yan aperture in eachend portion thereof; an

adjusting screw threaded into the bottom wall of each slot and having a reduced end that forms a shoulder, the reduced end of each screw being received in an aperture of the bar, and the shoulder of each screw bearing against the body of the bar; and return- Ving springs connected to said bar.

8. In a typewriting machine, the combi- Y nation of a machine frame provided with ways, a hollow sheet metal supporting bar which is substantially C-shaped in crosssection and is slotted transversely thereof to form a series of teeth, adjustable means for effecting a bodily adjustment of said bar in said Ways, a series of key actuated members, and a series of returning springs therefor, each spring at one end being hooked over a tooth on the bar and at its opposite end connected with a key actuated l 2 member.
